Andromonoecy is a widespread sexual system in angiosperms characterized by plants carrying both male and bisexual flowers. In melon, this form controlled the identity of alleles at andromonoecious ( ) locus. Cloning gene reveals that andromonoecy results from mutation active site 1-aminocyclopropane-1-carboxylic acid synthase. Expression enzyme inhibits development organs not required for carpel development. A causal single-nucleotide polymorphism associated with was identified, which...
How flowers separate males and females Most flowering plant families have bisexual with both male female function. However, most members of the Cucurbiticeae family, which includes melons, cucumbers, gourds, unisexual flowers. To understand this difference in sex expression, Boualem et al. identified a cucumber gene expressed Mutations were associated solely By integrating finding into determination model, authors explain how can coexist same plant.

Summary The characterization of natural recessive resistance genes and virus‐resistant mutants Arabidopsis have implicated translation initiation factors the 4E family [eIF4E eIF(iso)4E] as susceptibility required for virus multiplication expression. To date, viruses controlled by these mainly belong to Potyviridae. Melon necrotic spot (MNSV) belongs Tombusviridae (genus Carmovirus) is an uncapped non‐polyadenylated RNA virus. In melon, nsv ‐mediated a source against all strains MNSV except...
Abstract Background A number of molecular marker linkage maps have been developed for melon ( Cucumis melo L .) over the last two decades. However, these were constructed using different sets, thus, making comparative analysis among difficult. In order to solve this problem, a consensus genetic map in was primarily highly transferable anchor markers that broad potential use mapping, synteny, and quantitative trait loci (QTL) analysis, increasing breeding effectiveness efficiency via...
Background Fruit ripening and softening are key traits that have an effect on food supply, fruit nutritional value consequently, human health. Since ethylene induces of climacteric fruit, it is one the main targets to control over leads deterioration. The characterization pathway in Arabidopsis tomato identified genes ripening. Methodology/Principal Findings To engineer melon with improved shelf-life, we conducted a translational research experiment. We set up TILLING platform monoecious...
Aphis gossypii is a polyphagous sucking aphid and vector for many viruses. In Cucumis melo, dominant locus, Vat, confers high level of resistance to infestation viruses transmitted by this vector. To investigate the mechanism underlying double resistance, we first genetically dissected Vat locus. We delimited single gene that encodes coiled-coil-nucleotide-binding-site-leucine-rich repeat (CC-NBS-LRR) protein type. validate genetic data, transgenic lines expressing were generated assessed...
Male and female unisexual flowers evolved from hermaphroditic ancestors, control of flower sex is useful for plant breeding. We isolated a female-to-male transition mutant in melon identified the causal gene as carpel identity <i>CRABS CLAW (CRC)</i>. show that master regulator determination cucurbits, transcription factor <i>WIP1</i> whose expression orchestrates male development, recruits corepressor TOPLESS to <i>CRC</i> promoter suppress its through...
Abstract Fruit ripening and abscission are associated with an ethylene burst in several melon (Cucumis melo) genotypes. In cantaloupe as other climacteric fruit, exogenous can prematurely induce abscission, production, ripening. Melon genotypes without fruit or also exist are, therefore, non-climacteric. the nonabscising PI 161375, failed to stimulate loss of firmness, expression all target genes tested. However, 161375 etiolated seedlings displayed usual ethylene-induced triple response....
Partial resistance to downy mildew (Pseudoperonospora cubensis) and complete powdery (Podosphaera xanthii races 1, 2, 3, 5 Golovinomyces cichoracearum race 1) were studied using a recombinant inbred line population between ‘PI 124112’ (resistant both diseases) ‘Védrantais’ (susceptible line). A genetic map of melon was constructed tag these resistances with DNA markers. Natural artificial inoculations Pseudoperonospora cubensis performed replicated in several locations. One major...
Understanding the evolution of sex determination in plants requires cloning and characterization genes. Monoecy is characterized by presence both male female flowers on same plant. Andromonoecy carrying bisexual flowers. In watermelon, transition between these two sexual forms controlled identity alleles at A locus. We previously showed, Cucumis species, melon cucumber, that from monoecy to andromonoecy results mutations 1-aminocyclopropane-1-carboxylic acid synthase (ACS) gene, ACS-7/ACS2....
Abstract In flowering plants, the predominant sexual morph is hermaphroditism, and emergence of unisexuality poorly understood. Using Cucumis melo (melon) as a model system, we explore mechanisms driving forms. We identify spontaneous mutant exhibiting transition from bisexual to unisexual male flower, causal mutation Harbinger transposon impairing expression Ethylene Insensitive 2 ( CmEIN2 ) gene. Genetics transcriptomic analysis reveal dual role in both sex determination fruit shape...
A new linkage map of Cucumis melo, derived from the F 2 progeny a cross between PI 414723 and C. melo 'TopMark' is presented. The spans total 1421 cM includes 179 points consisting random amplified polymorphic DNA (RAPD), fragment length polymorphism (AFLP), inter-simple sequence repeats (ISSRs), simple (SSRs), restriction (RFLP) markers. also an aphid resistance trait (Vat) sex type gene, andromonoecious (a), two which are important in breeding control hybrid seed production, as well...
Melon (Cucumis melo) is an important vegetable crop from the Cucurbitaceae family and a reference model specie for sex determination, fruit ripening vascular fluxes studies. Nevertheless, nature role of its epigenome in gene expression regulation more specifically determination remains largely unknown. We have investigated genome wide H3K27me3 H3K9ac histone modifications dynamics, five melon organs. were mainly distributed along gene-rich regions constrained to bodies. was preferentially...
